Abstract: A magnetic shelter frame is adapted for detachably mounting on a primary spectacle frame which includes a frame body having a pair of lens rims for mounting a pair of lenses in position wherein each lens rim includes a frame locker for securely locking up the lens within the respective lens rim. The frame body includes a primary bridge connected between the two lenses and two side extensions provided at two outer sides of the lenses respectively each having a hinge portion rearwardly extended therefrom for pivotally coupling a temple. The shelter frame for supporting two auxiliary lenses includes a bridge extended between the two auxiliary lenses, two side interlocking means provided at two sides of the auxiliary lenses respectively for interlocking with the two frame lockers of the frame body of the primary spectacle frame so as to securely mount the shelter frame in front of the primary spectacle frame.

Abstract: A shelter frame kit is adapted for detachably mounting in front of a primary spectacle frame wherein the shelter frame kit for supporting two auxiliary lenses includes a bridge extended between the two auxiliary lenses, two shelter arms having two pivot hinges affixed on upper sides of the two auxiliary lenses respectively, and two interlocking means provided at two ends of the two shelter arms respectively for interlocking with two rim lockers of the primary spectacle frame such that the auxiliary lenses are adapted for pivotally folding from a closed position to an open position, wherein in the closed position of the shelter frame kit, the two auxiliary lenses are respectively positioned in front of two lenses of the primary spectacle frame, and in the opened position of the shelter frame kit, the two auxiliary lenses are 180-degree flipped over the two lenses of the primary spectacle frame respectively.

Abstract: A universal shelter frame for attaching to a primary spectacle frame having two primary lenses mounted thereon, wherein the universal shelter frame includes a pair of shelter lenses each having an inner side facing with each other, a pair of connecting members which are affixed to the two inner sides of the two shelter lenses respectively, and an adjustable bridge arrangement connected between the two shelter lenses together for supporting the two shelter lenses apart and forming a bridge distance between the two shelter lenses. The adjustable bridge arrangement includes at least one compression unit for enabling the adjustable bridge arrangement to be compressed to contract the bridge distance in order to mount the shelter frame on the primary spectacle frame by attaching the two connecting members to two inner edges of the primary lenses of the primary spectacle frame respectively.

Abstract: An auxiliary interlocking frame is adapted for mounting on primary eyeglasses. The primary eyeglasses include a frame for mounting a pair of lenses in position. The frame includes a bridge connected between the two lenses, and two magnetic side extensions each having a hinge portion extended rearwardly therefrom for pivotally coupling a temple. The auxiliary interlocking frame for supporting two auxiliary lenses includes a clip-bridge which is extended between the two auxiliary lenses for fitting behind the bridge of the frame of the primary eyeglasses, and two side interlocking devices which are provided at two outer sides of the two auxiliary lenses respectively for interlocking with the two magnetic side extensions of the frame so as to securely mount the auxiliary interlocking frame on the primary eyeglasses in detachable manner.

Abstract: An interlockable magnetic shelter frame is adapted for mounting on a primary spectacle frame which comprises a frame body for mounting a pair of lenses in position.
